drm/xe/guc/tlb: Flush g2h worker in case of tlb timeout

Flush the g2h worker explicitly if TLB timeout happens which is
observed on LNL and that points to the recent scheduling issue with
E-cores on LNL.

This is similar to the recent fix:
commit e51527233804 ("drm/xe/guc/ct: Flush g2h worker in case of g2h
response timeout") and should be removed once there is E core
scheduling fix.

v2: Add platform check(Himal)
v3: Remove gfx platform check as the issue related to cpu
    platform(John)
    Use the common WA macro(John) and print when the flush
    resolves timeout(Matt B)
v4: Remove the resolves log and do the flush before taking
    pending_lock(Matt A)
